They're particularly good at getting orders right compared to some other restaurants, so the additional value here to me is negligible. It's actually negative value to me, since if I can do a transaction without having to sign up, that's what I prefer. The value is entirely in the other direction: McDonald's wants to monetize their customer's identity information.
